SPECIFICATION forming part of 'Letters Patent No. 699,454, dated May 6, 1902.

Application tiled January 28.1902. Serial No. 91,554. (No model.)

Lo @ZZ whom, zit may concern: frame and clevis, the colter maybe adjusted Be it known that I, FRANK D. COOK, a citias desired. The object in carrying the colzen of the'United States, residing'at Termiter on the clevis as shown is that it may al- 55 nus, county of'San Joaquin, State of Califorways operate in the line of draft irrespective nia, have invented an Improvement in Culof whatever angle the clevis may be disposed tivator Attachments; and I hereby declare 'in relation to the axis of thecultivator. A the following to be a full, clear, and exact bar is secured to the lugs G of the-upper description of the same. clevis-plate. This bar is perforated at 16, so 6o My invention relates to improvements in as to be adjustable. The projecting portion 1o farmingimplemenlsofthe typeknown ascul of this bar is curved upwardly, as shown at tivators7 ant weeders. It is particularly 17. A b'a`r or arm 18, extending lengthwise intended for use in connection with the tillot the machine, is pivoted in a bracket 19 on ing of corn, beets, and the like where it is dethe end of the curved bar. At Ithe rear end sirable to cultivate close up to the row on of the arm 18 is carried a shovel 4: by means i5 either side. of a standard 20, adjustably secured in a clip It consists inthe combination, with a main 2l. This clip has a series of transverse percult-ivator-frame, of a supplementary lateral 'forations 2.2, whereby the clip may be bolted adjustable frame by which the cultivator is tothe arm 18 at any desired angle. The stand- 7o` adapted to straddle the row andY of an im` ard20is perforated, as at 23;so4`that the depth 2o proved form of clevis attachment and draftat which the shovel is to operate maybe reguequalizing means. lated. The standard is slidable in a groove in It comprises details which wilt he more the clip,and the two are secured together by fully set forth hereinafter, having reference means of ashort bolt 24, as shown in-Fig. 4. to the accompanying drawings, in which-' A br'acket'25, having two separated members z5 Figure 1 is a sideelevation.

This A represents a main cultivator-frame conrod extends throughtheloop27 of the bracket sisting of bars pivotally secured at their for- 25, and the outward swing of the lateral arm ward end and extending backward diver- 18 is limited by means ofva key 30, fitting the 35 gently, being held in proper relation to each .perfofrations of the rod. In order to maintain other by means of the adjustable braces 2. the-rear end of the arm in proper position, so Suitable handles 3 are provided by which the `that theshovel a" will befsuitably separated machine may be guided. Cultivating or from its adjacent complementary shovel 4b 9o weeding shovels or plows LL are'secured to on the main frame and accommodate the row 4o this frame, as shown. The forward end ofthe in the interveningv space, I provide a stiff frame-bars are held between-the two plates curved spring 31,` which has one end secured 5 5', the upper of which is provided with the to the arm at 32 and the other to the bracket perforated lug 6 and also with the curved 19. The tendency of this spring is to turn 95 flange 7 This liange is concentric with the thearm 18 outwardly.

45 pivot 8 of the clevis 9 and hasa ,seriesotf This device is admirably adapted to the perforations 10. By means of a boltll the cultivation of corn, beets, and other Vegetaclevis may be set at any angle in relation to bles where it is desired to cutout weeds and the axis of the cultivator, so that the line of work the ground close up on either side of the 1Go draft may be equalized for the purpose to be row.` The curved portion 17 of the transverse 5o hereinafter seen. Aeolter-frame 12 is pivbar 16 allows the machine to ride 'overthe tops oted to the elevs at 13, and by means of a of the corn Without injuryvto the latter.A bolt 14, passing through perforations in the `Where cultivatingin orchardsor vineyards and it is desired to cultivate around the trees, the flexible arm 1S permits the machine to be driven straight ahead instead of having to turn out for every tree. In such cases I provide suitable means by which the rear end of the arm may be drawn in toward the main frame whenever any obstruction is approached and be again released when the obstruction is passed. The means are here shown as a cord 33, having one end secured to the bracket 25 at 34E and running through suitable guides 35 to the hand ot' the operator. The end of the arm carrying the shovel 4 is drawn in toward the main frame by a simple pull on the cord. This allows the operator to work the ground close up to and completely around the trees and obviates the necessity of guiding his team in and about each tree, as is ordinarily the case. The disposition of this supplemental frame upon one side oi the cultivator has a tendency to throw the line of draft to one side of the axis ot' the cultivator. Hence the purpose of the curved perforated plate 5 and clevis attachment.

. Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is

l. A cultivator consisting in combination of a main plow-frame, a supplemental lateral frame pivoted thereto, plows or 'shovels adjustable on the lateral frame, a segmentallyflanged plate upon the main frame, a clevis v pivoted thereon, said ilange concentric with the pivot of said clevis, means for uniting said clevis and flange so that the former may stand at any desired angle in relation to the axis of the cultivator, and a colter carried by said clevis.

2. In a cultivator, the combination of main and supplemental plow-frames of a clevis attachment upon the main frame consisting of upper and lower plates united to said frame, a clevis pivoted thereon, said upper plate having a segmental iange concentric with the pivot of said clevis, perforations in said clevis and flange, and means for securing said parts rigidly together.

3. The combination in a cultivator with the main frame thereof, of a pivoted, supplemental, lateral frame, shovels or plows .carried by said frames, and means including a spring member by which said lateral frame may be maintained at a distance from the main frame. Y

4. The combination in a cultivator of a main plow-frame, a transverse support carried thereby, and a supplementary springpressed plow-frame pivoted to said support, said frames adapted to straddle a row.

5. The combination in a cultivator oi"l a main frame, a transverse bar secured thereon, a spring-pressed arm pivoted to the end of said bar and plows or shovels carried by said frame and bar.

6. The combination in a cultivator of a main plow-frame, a transverse bar adjustably secured to the forward end of said frame, an arm pivoted to the end of said bar, a standard having an adjustable tilting and Vertical movement secured to said bar and plows or shovels secured to said standard.

'7. The combination in a cultivator of a main plow-frame, a supplemental lateral frame secured thereto but adapted to have an intervening space therebetween, plows or shovels carried adjustably on said lateral frame, and spring means by which the two frames are normally separated.

8. The combination in a cultivator of a main plow-frame a transverse bar adjustably secured to said frame, a segmental projecting extension of said bar, an arm pivoted at the end of said extension, a spring adapted to press said arm outwardly from the frame, a plow orf-shovel ad justably carried on the rear end of said arm, a guide-rod extending outwardly from the frame and adapted to support the shovel end of said arm, means by which the outward or divergent movement of said arm may be limited and means connecting with the handles of the frame by which the arm may be drawn in toward the frame.

9. A cultivator consisting in combination of a main plow-frame, guiding-handles thereon, a curved bar extending outwardly from the forward portion of said frame, an arm pivoted to said bar, a spring by which said bar is normally held away from said frame, plows or shovels adjustably carried on the end of said arm, means connecting with the handles by which the bar may be drawn in toward said frame, a curved flanged plate secured to the frame, a clevis pivoted on said plate and adapted to be held at any desired angle-in relation to the axis of the cultivator and a colter carried on said clevis.

In witness whereof I have hereunto set my hand. A
